COUPLIN G-RIN G FOR REFBIGER ATOB-LIN IN GS.

Specification of Letters Patent. Patented June 4, 1912'. Application filed February 23, 1912. Serial No. 679,403.

To all whom it may concern Be it known that I, WALTER H. Wnrrrmn, a citizen of the United States of America residing at Grand Rapids, in the county of Michigan, have invented certain new and useful Improvements in Coupling-Rings for Refrigerator-Linings; and I do hereby declare the following to be a full, clear, and exact description of the made to fit elongated openings semi-circular at the ends and having parallel sides. The edges of the material are extended outward at the ends to form a circumferential rib as at 5 and at the sides of the rin are folded in reverse position upon the folded portions 4 as at 5* to form channels to receive the flanfges 2 of the linings. The ring is'also pre erably provided with a coupling plate 7 where the ends are joined to assist in holding the same in alinement and to more comp'letely close the opening where.the ends abut aga-inst each other, but this coupling is whichit appertains to make and use the same.

My invention relates to improvements'in coupling rings for refrigerator linings and its object is to improve upon the device shown in patent issued to me No. 970,672, dated Sept. 20, 1910, and its object is to provide a device adapted to be made of sheet metal and more easily adapted to any irregularity in the flanges, to provide the same with improved means for retaining ferred. The outer portions of the portion 4 are also formedsomewhat concave as at 6, to secure more intimate contact of the fold ed margins of the ring with the flanges 2.

Vhen the device is assembled as illustrated in F i s. 4 and 5 the ring forms a smooth roun ed symmetrical-lining to the the same in place and to rovide the same opening and is effectually retained in place with various'new and use 1 features heretherein by engagement of the ed es of the inafter more fully described and particuflanges 2 with the portions 4 an 5 of the larly pointed out in the claims reference bering.

ing had to the accompanying drawings, in What I claim is which: 1. A coupling ring for. refrigerator lin perspective view of my im- Figure 1 is a ring and adjacent portions 1ngs,comprisin a sheet metal structure proved coupling having a middle portion form ng a lining for an opening, marginal portions folded on the outside of the middle portion and outwardly extended edge portions forming a circumferential rib or flange on the outside of the ring. 2. A coupling ring for refrigerator linlugs: having a middle portion forming a lining or an opening, marginal portions folded on the outside of the middle portion and an edge portion outwardly extended to for retaining means for the ring.

3. A coupling ring for. refrigerator linings, comprising a middle portion forming a lining to an opening, marginal portions folded upon the outside of the middle portion and edge portions refolded upon the Fig. 3 a detail of a portion of the same in elevation; Fig. 4 an enlar ed broken sectional detail taken transverse y of the ring on line H of Fig.2; and 5 a similar View through the ends of the ring on line 55 of Fig. 2. 1 Like numbers refer to like parts in all of t e figures.

1 represents a portion of a refrigerator lining adjacent to an opening in the wall-of for op osite sides of the wall and provided anges 2 extending within the opening in the wall (the refrigerator wall being omitted herein). These anges are pr -ferwhen in place i. the space there-between to receive the outwardly extended margin to receive flangeson the refrigerator lini s. 4.'A cou ling ring for refrigerator 11nings, comprising a sheet metal structure hav portion forming a lining for an openin formed semi-circular at the ends and para lel at the sides, marginal portions folded upon the outside of the midle portion, edge portions extended My improved ring consists of a sheet metal structure having the inner portion 3 slightly convex toward the interior of the portions 4 folded upon the outside of the inner portion. These rings are preferably H. WHITTIER, 0F GRAND RAPIDS, MICHIGAN, ASSIGNOR TO GRAND RAPIDS OF GRAND RAPI marginal portions toform channels ada ted outward a middle portion to form a limng f 0 posite the ends and folded upon the marginal ortions opposite the sides to form cha-nne s adapted to receive flanges on the refrigerator linings.

5. A coupling rin for refrigerator linings, comprising a s eet metal ring having openingand edge portions upon the outside of the middle portion adapted to enter between t-he flanges of a refrigerator lining to 15 hold the ring in place.

In testimony whereof I affix my signature in presence of two witnesses.
